Klizan was quickly up 5-0 in first set, but he had to save bp´s on every game on serve while he converted both BP opportunities. Had setpoint at 5-1 40*-30, but fell down to 5-3 15*-40 - then he won next four points to clinch first set 6-3.

In second set were plenty of close games, Klizan was up 3-2 w/break, then down 3-4 and serving. Holded, broke and served for the match. At 5*-4 saved BP (obviously) and won 6-3 6-4.

Break point conversion says it all - Klizan 4 from 4 while Belluci 2 from 11.

Cilic or Kubot in second round.

So, basically he was allways way up in the match, only had trouble closing out the sets. That story tells me it was actually easier than the scoreline says.
